Abstract

A pad for cleaning and polishing a wide variety of surfaces is disclosed. The pad includes two outer sheets made of filament material, an inner sheet made of elastic material and sandwiched between the two outer sheets, and two mesh sheets, wherein said inner sheet and said outer sheets are sandwiched between said mesh sheets. The filament material is rugged enough to effectively remove contamination that is firmly adhered to the surface to be cleaned, yet it is also fine enough to avoid damage to delicate surfaces and to be suitable for polishing purposes. Also, the elastic material is flexible enough to allow the filament material to be forced through the gaps in the mesh sheets and into contact with the surface to be cleaned and/or polished.
